Orbilia on herbaceous stems (Galium?)
Enrique Rubio, 21-10-2021 21:09
Enrique RubioI would be grateful for an opinion on this Orbilia which forms tiny, pulvinate, non-flattened ascomata on herbaceous stems, most probably Galium mollugo, at 1700 m altitude. Secretions can be seen at the margins but no true glassy processes.
Many thanks in advance.

Could you please send me in higher resolution?

Sounds like O. subtrapeziformis, but the spores are not very acute above and the herbaceous substrate is unusual.

Hi Zotto
Sent by wetransfer. The collector was Jesús.

Re : Orbilia on herbaceous stems (Galium?)
Thanks! The problem is always to distinguish O. subtrapeziformis and O. obtusispora. O. trapeziformis is excluded by spoore length, so I tend to believe this is O. obtusispora.

I tried my key and unequivocally arrive at O. obtusispora, except that this would be the first sample on a herb.

But: is the substrate correct? couldn't this be a very thin, very rotten woody twig?

Hi Zotto
It was undoubtedly a herbaceous stem. The only doubt is whether it was a Galium or not.

I cannot imagine that a rotten Galium stem looks like this but I may be wrong.

Re : Orbilia on herbaceous stems (Galium?)
There were many stems of Galium mollugo on the site and very close by, and although I cannot be sure that they belonged to this species, the substrate was certainly not woody at all.
